SPOOL SUPPORT FOR rwrs'rms MACHINES AND THE LIKE.

Application filed March 219, 1927. Serial No. 179,367.

My invention relatesto an improved support for the spools employed on the twisting machines and the like, wherein the spools are rotated at a relatively high speed while the twisted, or other material, is wound on the spools by fliers rotating at a slightly" higher speed thanthe spools themselves. In such machines as heretofore constructed each spool has been freely rotatable on avertical spindle carrying the flier with one head of the spool resting on a rail to which an up and down motion is imparted in order to traverse the material being wound on the spool.

With this construction there is naturally considerable friction between the head of each spool and the supporting rail and between the body of'the spool and its spindle, and when the machine is operated ata high speed, a considerable amount of heat is generated by this friction between relatively movable surfaces. Inasmuch as the wooden spools heretofore employedtend to char and warp, due to the heat generated, it has been found that a very definite limitation is imposed on the speed at which machines of this type can be safely operated when employing spools constructed of wood or other nonmetallic material having poor heat dis-' sipating qualities.

The object of the present invention is to provide an improved support for the spools of twisting machines and the like, whereby any heat generated. by the rotation of the spools is quickly dissipated, so that there is no appreciable heating of the spool and its associated parts, even when the machine is run at speeds not heretofore considered practicable. My improved spool support in addition to its heat dissipating properties is also so constructed as to insure that the associated spool will always be correctly alined on its spindle, thereby insuring the formation of an even winding on the spool. The above and other advantageous features of my invention will hereinafter more fully appear, reference being had to the accompanying drawings, in which Fig 1. is a View partly in vertical section and partly in elevation illustrating my invention with the associated parts of a twisting machine.

Referring to Figs. 1 and 2, my invention shown for purposes of illustration in connection with parts of a twisting machine, although it is to be understood that my invention may also be employed in connection with the support of rotatable spools employed on similar types of machines. In this particular embodiment of my inventioneach spool consists of a cylindrical barrel 1, preferably of wood, provided at'itsends with heads 2 composed of wood, compressed fibre, or any similar light weight material. A vertical spindle 3 extends through the bore 4; of the barrel 1, the spindle 3 being supportedat its top and bottom in suitable bearings 5, only portions of which are shown.

The spindle 3 carries a gear 6, whereby a rotative driving force may be imparted thereto from a source of power, not shown, and a flier 7 is also carried by the spindle and rotatable therewith. The flier 7 provides downwardly extending hollow legs 8, 8, through either one of which the material to be wound on the barrel 1 of the spool passes to the spool, as indicatedat 9. The material 9 is led downwardly through the upper por-' tion of the spindle 3 and emerges from an eye 10 to pass around a positively. driven,

take-up drum 11 before. passing into the leg 8 of the'flieri, As previously pointed out the spoolis free on its spindle 3 and is adapted to be positioned thereon by means of a spool rail 12 which isada-pted to have anup and down motion imparted thereto by means not shown, since it forms no part of the present invention. As the flier 7 is rotatably driven at a high rate of speed it slowly winds the twisted, or other material 9, on the barrel 1 while at the same time the spool turns at a rate only slightly less than that of the flier. The difference in speed between the IOU flier 7 and the spool results from the frictional retardation of the spool, and it diameter as toclosely receive a sleeve 13,

preferably composed of light rnetal that "readily conducts heat, such as aluminum,

and this sleeve '13 provides suitablebearing surfaces 14 at its ends for engagement With thespinclle 3. The sleeve terminates at its lower end in cir ula fians vv r p at 1 preferably formed integral therewith, the plate being in contact with the lovver head 2 of the spool.
